A friend of mine just bought a S&W No. 1, First Issue, 6th variation, serial number 8546. It is nicely inscribed to "McClure Branham" who he has identified as a railroad executive in Indiana, 1817-1869. Unfortunately, all that he has is the frame, and the QUESTION IS, What about this steel frame? All info we can find tells us these pistols should have a brass frame. Are others with steel frames known?
